Gomphonema Ehrenberg e Gomphosphenia Lange-Bertalot (Bacillariophyceae) do Rio Maurício, Paraná, Brasil

Abstract: (Bacillariophyceae) from Maurício river, Paraná, Brazil. Biota Neotrop., 9(4): http://www.biotaneotropica.org.br/v9n4/en/abstract?inventory+bn00309042009. Abstract:The biogeography and morphological variability of Gomphonema and Gomphosphenia species are still poorly known in Brazil. Due to the secretion of mucilage by the apical pore fields, Gomphonema is a common genus in periphytic algal communities, being well represented in richness and density. Studied samples were removed from Potamogeton polygonus Cham… Show more

“…Ludwig & Flôres (1995;1997) conducted studies in rivers within the catchment area of the Segredo hydroelectric power plant, and Brassac et al (1999) studied the area around the Salto Caxias hydroelectric power plant, both identifying centric diatoms. Similar studies were conducted by Tremarin et al (2009a), in the Maurício River, and by Santos et al (2011), in the Salto Amazonas River and in an artificial lake in the municipality of General Carneiro. Other studies of diatoms in the Iguaçu River were performed by Brassac & Ludwig (2003;, Ludwig et al (2008) and by Bartozek et al (2013).…”

“…Difere de G. coronatum Ehrenberg pela extremidade apical mais inflada (Kociolek 2011). Já foi reportada para o Estado do Paraná (Procopiak et al 2006, Tremarin et al 2009, Bertolli et al 2010, região Centro-Oeste brasileira ) e para o Estado de São Paulo (Marquadt 2012). É a primeira citação de ocorrência da espécie para a área de estudo, onde ocorreu apenas no Reservatório de Jurumirim, em 21% das estações de amostragem (tabela 1).…”

“…Há registros de G. laticollum Reichardt para o Estado do Paraná, porém, na maioria, como G. truncatum Ehrenberg, exceto ao registro de Lozovei & Shirata (1990) que não pôde ser confirmado em razão da ausência de descrição, ilustração e ultraestrutura da valva (Tremarin et al 2009). A espécie também foi reportada para esse Estado como G. truncatum var.…”
